Cold Climate Grape Cultivar`S Physiological And Gene Expression Responses To Low And Freezing Temperatures, Turhan Yilmaz
Cold Climate Grape Cultivar`S Physiological And Gene Expression Responses To Low And Freezing Temperatures, Turhan Yilmaz
Electronic Theses and Dissertations
Grapevine (Vitis Vinifera), widely cultivated in the world and USA, is a significant and valuable fruit crop. After cold climate grapevine cultivars were released by breeding programs in the 1990s, the production of grapes expanded in the Northern cold climate region of the US. The objectives of this study were to test 1) freezing tolerance and chilling fulfillment, 2) the effect of pruning methods on yield and winter survival, and 3) transcriptomic changes in natural and controlled chilling conditions during chilling requirement fulfillment in cold climate grapevine cultivars. Pruning methods, spur (SP), short cane (SC), and spur plus short cane …
Exploring Phenotypic Diversity And Quantitative Trait Loci Mapping For Root Architecture, Freezing Tolerance, Chilling Fulfillment, And Photoperiod Traits In Grapevine Populations, Dilmini Alahakoon
Electronic Theses and Dissertations
Grapevine (Vitis species) is one of the most valuable fruit crops widely cultivated throughout the United States of America (USA). Grape and wine industries in the northern USA have been expanding rapidly with the demand for quality wine grapes that can be grown in Northern cold climate regions. As most popular cultivars are freezing sensitive, the development of new cultivars for the region continues through breeding. In this study, we evaluated grapevine root system architecture, freezing tolerance, and bud break in different genetic backgrounds in natural or controlled environments. The dissertation research objectives were to explore trait phenotypic variation and …

Electronic Theses and Dissertations
Freezing injury, caused by freezing temperatures in the late fall, midwinter, or early spring, can result in significant loss to grape growers. The damage may range from the partial damage of parts of the plants to the total death of the plant, and may vary between years. Freezing tolerance is a multi-genetic, complex quantitative trait that involves many related traits like dormancy induction, growth cessation, acclimation, deacclimation and bud break. Developing an understanding of the genetics behind the complex trait requires connecting the phenotype with the genotype to enable discovering the underlying genes that can contribute to quantifiable differences between …
